"As I recall TMI is a Babcox and Wilcox design"
Yes it is. I had breakfast many times with the engineers, etc. They would laugh at us when we talked about potential problems.
These days, including today, I go fishing next to TMI. The small mouth bass seem to love the warm waters coming from the island. (no jokes about glowing and genetically mutilated fish are necessary, we have heard them all)
Small mouth Bass are sooo much fun to catch. I found that the frog colored Jitterbug worked very, very well in New England, Lake Champlain to be exact. The one with a white belly, olive drab back with black spots on top. Used yellow Shysters off the rocks after the bass stopped feeding. We cleaned house. Those were the days. Sigh!
